It seems that in my Cubase 5.2 the range in which pitches are recognized and editable within Variaudio are limited to C5 (which equals c’’’).
Naturally, instrumental parts are often located in a higher range. Sometimes even vocal parts (the “Queen of the night” aria goes up to f’’’! 
).
Am I doing something wrong, is there a way to specify the range, is this addressed in C6, or do I just have to live with it?
Bump. No ideas?
The manual states somewhere that Variaudio is basically developped for vocals, not for instruments. And if you don´t have any detection above C5, then that´s the end of the range. And no there is no way to specify the range, and I think this has been discussed here already…
Thank you for your answer, I found the thread you mentioned (it’s about the bottom limit, interestingly), and it seems there’s nothing to fix here.
Would be a rather valid request for an addition in later versions though.
